Definitions

  • the invention relates to a container having a mouth, the rim of which having an upper surface defining a practically flat plane.
  • a container of this type is adapted to be sealed by a cap having an upper panel, a sealing channel surrounding this panel filled with a sealing compound and a depending skirt adjoining the channel.
  • the radial width of the sealing channel has to be in excess of the radial width of the upper surface of the mouth rim in order to obtain a suitable sealing.
  • the cap is fastened by means of from the depending skirt inwardly protuding fastening means such as screw threads and particularly by inward, regularly about the circumference distributed protusions in the depending skirt.
  • the said inward protusions or fastening means are fastened below outward protusions arranged on the outside of the mouth, such as a continuous collar or complementary screw threads.
  • the invention provides for a remedy for this problem by providing the container of the type as described with a continuous rim on the upper surface of the mouth and extending along the entire perifery.
  • a container of this type can be sealed by using a cap having an upper panel, a sealing channel surrounding this panel and being filled with a sealing compound, and a depending skirt adjoining the channel.
  • the inner diameter of the sealing channel has to be smaller than the inner diameter of the rim, but larger than the inner diameter of the upper surface of the mouth, while the depth of the sealing channel has to be in excess of the height of the rim over said upper surface of the mouth. Then a sterilization or pasteurization treatment can be effected without damaging the seal of detrimenting the mechanical fastening.
  • the cap being applied on the container practically bears with its flat part adjoining the sealing channel on the upper surface of the mouth inside the rim.
  • the sealing compound is not or only slightly further loaded. Accordingly flow of the sealing is prevented and a perfect seal is maintained.
  • the construction according to the invention has the additional advantage that solid parts of the contents of the container, such as vegetables and fruit, during the closing and sealing process are better cut by the rim than by the known construction. Moreover the same sealing compound can be used for whichever purpose and as a considerably narrower sealing channel is used, only a fraction of the previously required amount of the sealing compound is required now.
  • the radial width of the rim amounts to 1/5 to 1/2 of the radial width of the entire upper surface of the mouth; particularly the radial width of the rim is from 1 to 3 mm.
  • the radial width of the sealing channel is in excess of the radial width of the rim though smaller than the radial width of the upper part of the mouth.
  • the invention relates to a cap having an upper panel, a sealing channel surrounding this panel and being filled with a sealing compound, and a depending skirt adjoining the channel and being distinguished over the known caps of this kind in that the sealing channel has a width comprised between 1,5 and 4 mm and is with its inner perifery directly adjoining a flat part of the upper panel.
  • the sealing channel being in radial section about arc shaped in a preferred embodiments, flowingly merges into the depending skirt at the outer perifery, whereas it at the inner perifery abruptly is connected to the adjoining flat part of the panel.
  • FIGS. 1A and 1B are a perspective view, partly sectioned, of the upper part of a container and a cap for closing it,
  • FIG. 2 is a sectional view of a part of a sealed container.
  • FIG. 1A-B a mouth of a glass jar 1, such as for preserving vegetables and fruit, and a cap 2 for sealing said jar are shown.
  • the shape of the jar is not critical and the mouth opening may be both narrow and wide.
  • the mouth presents at its outer surface as usually a collar 3 for fastening the cap 2 and has at its upper side a flat surface 4, a periferal upstanding rim 5 being provided on said surface adjacent the outer edge thereof.
  • the rim 5 is about arc shaped.
  • the radial width a of the rim 5 is for jars of commonly used dimensions about 1/2 to 1/5 of the radial width b of the entire upper surface of the mouth in order that a sufficiently wide supporting surface for the cap 2 remains (see FIG. 2).
  • a suitable radial width a of the rim is from 1 to 3 mm.
  • the jar 1 can be sealed with a metal cap 2, having an upper panel 6 showing a usual profile, though being practically flat, a sealing channel 8, filled with sealing compound 7 and being adjacent the outer perifery of the panel 6, and a depending skirt 9 adjoining the channel at its outer periphery.
  • the sealing channel 8 is at its inner periphery contiguous to the flat annular portion 10 of the upper panel 6. After the cap has been provided on the jar the annular portion 10 will practically rest on the upper surface 4 of the mouth.
  • the dimensions of the sealing channel 8, of the rim 5 and of the flat portions of the mouth and the cap, 4 and 10 respectively, have to be suitably chosen: the inner diameter d of the sealing channel 8 is smaller than the inner diameter e of the rim 5 and larger than the inner diameter f of the upper surface 4 of the mouth; the radial width c of the sealing channel is in excess of the radial width a of the rim 5 though smaller than the total radial width b of the upper part of the mouth. In practice the radial width of the sealing channel 8 will be from 1,5 to 4 mm.
  • the invention is applicable both to ventilating and non-ventilating closures, while it does not need any elucidation that other fastening means than those depicted in the drawings and described in the specification can be used.
